Sorry xwb,
according to my textbook on Fortran you can perform operations on complete arrays, provided they are of the same size.
Even though I did not test them all, the following is correct:
real a(10),b(10),c(10),d
a = 0.0
b = 3.0
c = a + b
a = d * c
Lloydone,
I would recommend that you get yourself a copy of a good manual on Fortran. I use Stephen J. Chapman, Fortran 90/95 for Scientist and Engineers (McGraw-Hill series in general engineering).
(hopefully this is not thought to be advertising)
Even though it is adressed to engineers and scientists I found it quite comprehensible since most of the examples cover non-engineering problems. I guess that it would pay for you to spend those USD 40 (my guess, take a look in amazon for proper info) instead to have to wait for somebody to answer your forum question and delay your project each and every time you hit on some prob.
